  • Patent number: 7737086
    Abstract: A method is provided for producing a superconductive electrical conductor (7) in which a layer of an yttrium-barium-copper oxide (YBCO) is applied as a superconductive material onto a textured metal base directly or after prior application of a buffer layer, and is subjected to a heat treatment. To this end an interlayer of a metallic material which is compatible with the crystal structure of YBCO, or with the structure of a buffer layer suitable for the application of YBCO, is initially applied all around onto an elongate metal support (1). The support (1) provided with the interlayer is subsequently processed so that predetermined texturing is imparted to the interlayer as a metal base for the layer of YBCO material or for the buffer layer. The layer of superconductive YBCO material is then applied all around, directly onto the textured interlayer or onto the buffer layer previously applied thereon, and the heat treatment is finally carried out.
